seems that starting with 7.3.4 compression is available.
We tried in our lab and it might be working, BUT:
1) You just set a vol option, means existing data wont get compressed
2) New data copied into that volume will be compressed
3) df output is buggy:
storage> df -g
Filesystem total used avail capacity Mounted on
/vol/vol0/ 402GB 1GB 401GB 0% /vol/vol0/
/vol/vol0/.snapshot 100GB 0GB 100GB 0% /vol/vol0/.snapshot
/vol/vol_compression/ 100GB 97GB 2GB 98% /vol/vol_compression/
/vol/vol_compression/.snapshot 0GB 0GB 0GB ---% /vol/vol_compression/.snapshot
storage> df -S
Filesystem used compressed a-sis %saved
/vol/vol0/ 1089724 0 0 0%
/vol/vol_compression/ 102702580 60620532 0 37%
Any of you guys already messed around with it?

While the technology to perform volume compression has been in ONTAP 7.3 for a while, you can't actually enable it until ONTAP 8.0.1.
I know its confusing because you can see the compression option listed under 'vol options'. However, the release notes should always be your definitive guide as to what new features exist in an ONTAP release.
